Your assumption would be correct for almost all motors in the kit except the globe motor (in my honest opinion).
For some reason (maybe someone knows specifically) the globe motor is VERY sensitive to side loads. In past years when my team used these motors, if the shaft was not supported on both ends we would ruin the motor, even if it was used rarely.
If it is possible (it looks failry easy) you might want to try and put a bearing supporting the shaft on the other end... even though you might not really need it... it seems like it serves an important enough function to deem the extra work beneficial... even if it only gives you peace of mind.
Hope that helps
